Improvement in horseshoes



UNITED LEONHABD JOERG, OF BROOKLYN, NEW YORK.

IMPROVEMENT IN HORSESHOES.

Specification forming part of Letters Patent No. 185,237, dated December 12, 1876; application filed October 13, 1876.

To all whom 'it may concern Be it known that I, LEONHARD JOERG, of Brooklyn, Kings county, in the State ot' New York, have invented certain new and useful Improvements relating' to Horseshoes, ot' which the following is a specification:

The advantages have long been appreciated of having one or more of the calks removable and exchangeable at will. As the condition of the ground suddenly changes from stony to icy, and back again, it is important to'enable the stableman to change the calks.

The accompanying drawings form a part of this specification, and represent what I consider the best means of carrying out the invention.

Figure l is a view of the working-surface of the shoe. Fig. 2 is a section on the line S S in Fig. 1. Fig. 3 is a side elevation, partly in section.

Similarletters of reference indicate like parts in all the figures.

A is the body ofthe slice. B is the toecalk, and O O are heel-calks. D D are the flattened anges or bearings, being a part of the calk B, and extending backward, so as to furnish ample bearings for nearly the entire width of the shoe at this point. D D are fastening-screws, which, it will be understood, are countersunk into the calks and tapped into the body of the shoe to form a strong fastening. E E E are nicely-turned projections of cast-steel, or other strong and hard material, iirmly welded in the shoe, and accurately tinished by milling, or otherwise, to a true cylindrical surface, with the point a little tapering. The adjacent surface of the shoe is milled or otherwise finished, to make a fair bearing for the calk quite up to the pin IJ. Each calk is finished with a fair bearing-surface,-adapted to press against the corresponding surface of the shoe, and with a hole adapted to tightly receive the pin E. The hole has a depth a very little in excess ot' the length of the projecting part of the pin. There may be two or more pins extending into each calk, and one ofthe calks may be thus equipped without the others.

I claim as my inventionrlhe toe-calk B, having side flanges D extending front and rear, with fastenings D set therein, one at each side of the calk in front, and others set farther back, in combination with a shoe, A, having the pin E firmly set therein and matched in a hole in the calk, as and for the purposes specified.

In testimony whereof I have hereunto set my hand this 10th day of October, 1876, in the presence of two subscribing witnesses.
